Hepatitis B Surface Antibody, Quantitative Test code(s) 8475 Question 1. What is the clinical indication for hepatitis B surface antibody quantitation? Question 2. What is the hepatitis B surface antibody? Question 3. How is the quantitative hepatitis B surface antibody (anti-HBs) test performed...
With acute HBV infection, after an incubation period of 4–10 weeks, HBsAg becomes detectable in the blood, typically with measurable HBV DNA [21]. Shortly after HBsAg becomes positive, the first antibody to core antigen (IgM anti-HBc) appears [22]. Because hepatitis B core antigen (HBcAg)...
How do you interpret HCV antibody "reactive” and HCV RNA “not-detected” results? Question 6. Is it possible to have HCV infection and have a non-reactive HCV antibody test result? Question 7. What proportion of HCV antibody-reactive specimens are found to contain HCV RNA upon reflex ...
Objectives To explore the clinical value of genotyping the hepatitis B virus(HBV) as a crucial approach to analysis of its clinical phenotypes. Methods Fasting venous blood was collected from 245 patients with hepatitis B or a related liver disease. HBV DNA was typed using an HBV genotyping test...
antibody,anti-CD8 monoclonal antibody and HBV epitopic pentamers(S183-191,S335-343),and examined with flow cytometry,then analyzed by software Cell-quest.The peak value of alanine aminotransferase(ALT) and HBV load was detected at acute phase of patients,and the correlation was analyzed.Results ...

Herein, we review our current understanding of the role of the humoral immune response in chronic HBV, both at the level of HBV-specific antibody production and at the phenotypic and broader functional level of B cells. The recent development of fluorescently labelled HBV proteins has given us ...
In the 1970s, an unknown virus was suspected for documented cases of transfusion-associated hepatitis, a phenomenon called non-A, non-B hepatitis. In 1989, the infectious transmissible agent was identified and named hepatitis C virus (HCV) and, soon enough, the first diagnostic HCV antibody tes...
